- rhetted. it is from lisa marshall. she wants to know why is the area in annapolis or areas near the water warmer than inland. i always thought it was colder. >> you have asked a question that is near and dear to tucker barnes' art. this is something we talk about almost every day as we are putting together the temperatures for the various areas because of the water. here is to answer it is tucker barnes. >> this is a great question and i've got the answer for you. the answer is that, depending on the time -- first, let's start ith there is a great interaction between the atmosphere and the oceans and water. and what happens is there is a lag effect. so water takes longer to either hold cool or warm air in the winter and the opposite happens in the summer. so this time of year, what happens is that the temperature of the water, because we have wed the very warm summer months, there is a lag. the temperatures this time of year are actually warmer than corresponding areas out to the west of the district. in the summertime, the opposite holds true so closer to the water, temperatures are cool

-related. it is from lisa in barryville, virginia. she says, i would like it know how much snow it take to equal an inchof rainfall. for example, two inches of rain would be how much snow? we actually got a similar question from another viewer named meg fetting. the general rule of thumb is that generally speaking, an inch of rain would equal 10 inches of snow. so for every tenth of an inch of rain, that would equal an inch of snow. however, that depend on the type of snow really. we have the wet heavy snows. we have the fine, powdery snow. that can throw the numbers off, correct, tucker? radio very wet snow, the ratio can be about six to one or six inches of snow for anen. of rain. a very dry snow across arctic regions, their ratios can get with a up there, 20, 30, 40 inches of snow for an inch of rain. it depends on how dry the atmosphere is. >> that is hy we say generally speaking. >> a good starting point. >> i believe tucker barnes and i did this last year. as long as we're talking about t we might as well talk about when we think we'll see the first snowfall. >> it is that time of season.
